ldn_mitm is a homebrew system module that allows Local Wireless mode games to function over LAN, and therefore over XLink Kai. ldn_mitm is developed by spacemeowx2 for Nintendo Switch systems running custom firmware (CFW) such as Atmosphère, ReiNX, or SXOS.

Installation in Atmosphère/ReiNX

  1. Download the correct ldm_mitm release for your version of Atmosphère
    ldn_mitm version Atmosphère version
    1.8.0 0.19/0.19.1
    1.7.0 0.16.1/0.16.2/0.17.0/0.18.0/0.18.1
    1.6.0 0.15.0/0.14.4
    1.5.0 0.14.0/0.14.1
    1.4.0 0.13
    1.3.4 0.11/0.12
    1.3.3 0.10
    If your version of Atmosphère is not listed please try the latest nightly release. (Download the 'sdcard' file, not the .elf)
  2. After downloading the zip file extract it on your computer. You will be presented with two folders; 'atmosphere' and 'switch'
